Application filed August 29;1924. Serial at. 734,901.

This invention relates to improvements in tile forming mechanisms, and has for 1ts object to provide mechanism of that character which will readily andefficiently form a tile, for example, of concrete.

In the particularvform of tile for which this machine is designed, known to the trade as French tile, the pallets are formed with the side edges relatively offset and constructed in coaction with the forming member to create a tile with such side edge portions relatively thin. iVith the rapidly oscillatin'g forming member which I use I have found that thedifference in linear velocity of the forming portions of such member at arranged the axis of the tile forming member at an incline withrespect to the plane of travel of the pallets, so that the linear velo'ci-' ty of the forming member at the sides of the tile is more nearly the same. fully These and other objects will be more set forth and described in v the following specification and shown in the accompanying drawings, in whichp Fig. I 's a transverse section through a tile making machine embodyinghmy invention.

Fig II is avertical section along the line 2-2 of Fig. I.

Fig. III is a perspective View of an inverted French tile.

Fig. IV is a vertical section taken along the line 4. i of Fig. 2.

Fig. V is a perspective of one of the pallets upon which these tile are formed.

In thedrawings 10 designates generally the supporting framework of a tile making machine, having the table portions 10 between which runs conveying mechanism comprising a pair of spaced Chains 11, upon which are supported pairs of parallel strips ,12, the members of each pair being slightly spaced to accommodate the separating plate 13. I I

A charging hopper, generally indicated by numeral 14, projects upwardly from the table and is attached thereto in a suitable manner. At the front and back this charging hopper is open at the bottom to permit the entrance thereinto and exit therefrom of the pallets 15, which are supported in their passage through the machine by the 7 socket 25.

supporting strips, as shown in Fig; 2; Conthe flattened patting or tamping portion 17 which first encountersthe charge upon the moving pallet. This tamper is formedon lts under surface to conform to the contour -icneu's'o. nannnnrt on CHICAGO, rumors, assrenoa 'ro ooncan'rn TILE Macrrrir 'crete' aggregate is supplied to the hopper 14,

of the tile to be formed, as illustrated in i Fig. 1. The forming, member 17 is secured by machine screws 19, or the like, to a transverse axis-shaft 20, which is journalle'd at one end in the supporting bearing 21, and

at its other in a similar bearing'22. 'Outwardly of the bearing 22 the shaft 20-is provided with a projecting crank arm 23',hav-

ing a removable cap 24 secured thereto by screws 2%, the cap and crank being provided with a spherical socket 25 having the apere ture 25 leading therefrom "to accommodate the intruded end of drive shaft 26, which is formed with the spherical or ball-shaped -headv26 seated in and oscillating in the This shaft 26 is reciprocatedat high spee'dby means ofan' eccentric 27 and associatedmecha nism. c

The pallets illustrated and described coact with the forming member to form what aretermed French tile 30, one of which is illustrated in inverted posltion in perspective 1n Fig. III.

forming member were horizontally ar,

ranged the difference in linear velocity at the side portions-would be so considerable as to affect the the formation of the file at its edges, resulting in the formation of defective tile. By. inclining-the axis of ro-c tation, as shown in the drawings,' the axis of rotation is broughtnearer to the low These tile. are formed with the side edge portions 30 and 30 side of the tile and moved farther from the high side of the .tile than if it Were horizontal andthis difference in velocity is reduced to such an extent that formation of satisfactory tile is not interfered With.

The inclined mounting of the supporting shaft- 20 necessitates a species of universal joint, so that I have provided a ball and socket connection With the driving shaft 26, as previously described.

It will be apparent that my invention is susceptible of modification, and I do not Wishto be restricted to the form shown eX- cept as defined in the appended claims.

What I claim is 2-- 1. In combination, pallet conveying and supporting means, a forming member located above said means and transversely to the direction of movement thereof, means to move said forming member about an axis, said axis being inclined with respect to the plane of travel of the pallets upon said supporting means.

2. In combination, pallet supporting and conveying means, a forming men 'ber lo cated thereabove, said means being oscillatable about an axis transversely arranged With respect to said means, said axis being inclined With respect to the plane of travel of the pallets upon said means, and means to oscillate said forming member.

3. In combination, pallet supporting and conveying means, a forming member located thereabove, said means being 0scillatable about an axis transversely arranged with respect to said means, said axis being inclined with respect to the plane of travel of the pallets upon said means, and means to'oscillate said forming member, said last named means comprising a supporting shaft carrying said forming member, a crank arm projecting therefrom and a reciprocating drive shaft operatively attached thereto.

4. In combination, palletsupporting and conveying means, a forming member located thereabove, said means being oscillatable about an aXis transversely arranged with respect to said means, said axis being in clined With respect to the plane of travel of the pallets upon said means, and means to oscillate said forming member, said last named means comprising a supporting shaft carrying said formingmember, a crank arm projectin therefrom and a reciprocating drive shaIt operatively attached thereto by a ball and socket joint.

5. In combination, pallet supporting and conveying means, a forming member located thereabove, said means being oscillatable about an aXis transversely arranged With respect to said means, said a'X1s being inclined I with respect to the plane of travellof the pallets upon said means, and means to oscillate said forming member, vsaid last named means comprising a supporting shaft carrying said forming member, a crank arm projecting therefrom and a reciprocating drive shaft operatively attached thereto, said drive shaft having a ball portion, said arm being provided with a socket engaging said ball portion. I

6. In combination With a pallet having its sides relatively offset, a supporting and conveying means for said pallet, aforming member located'transversely of said conveying means and movable about an axis inclined With respect to the plane of travel of said pallet. i x

In Witness whereof, I hereunto subscribe my nameto this specification. I
